Fulfill the covenant of Allah, when you make a covenant and do not break your oaths after they have been confirmed (by swearing in His Name) for you make Allah your surety. Allah has knowledge of what you do. (91)

Do not be like the woman who breaks her thread, after it is firmly spun into fibers, by taking your oaths as mere mutual deceit, one nation being more numerous than the other. Allah tries you with it. On the Day of Resurrection, He will clarify to you everything on which you were at variance. (92)

Do not take oaths to deceive each other, lest your foot should slip after its firmness, lest you should taste evil, for you barred others from the Path of Allah, and lest a mighty punishment awaits you. (94)
